HP Serviceguard Extension for RAC (SGeRAC) # groupadd oinstall # groupadd dba # groupadd oper

Prerequisites for Oracle 10g, 11gR1, or 11gR2 (Sample Installation)

The following sample steps prepare an SGeRAC cluster for Oracle 10g, 11gR1, or 11gR2. Refer to the Oracle documentation for Oracle installation details.

1.Create inventory groups on each node.

Create the Oracle inventory group if one does not exist, create the OSDBA group, and create the Operator Group (optional).

#groupadd oinstall

#groupadd dba

#groupadd oper

2.Create Oracle user on each node.

#useradd -u 203 -g oinstall -G dba,oper oracle

3.Change the password on each node.

#passwd oracle

4.Create symbolic links.

Required if Motif 2.1 Development Environment Package is not installed.

#ln -s /usr/lib/libX11.3 /usr/lib/libX11.sl

#ln -s /usr/lib/libXIE.2 /usr/lib/libXIE.sl

#ln -s /usr/lib/libXext.3 /usr/lib/libXext.sl

#ln -s /usr/lib/libXhp11.3 /usr/lib/Xhp11.sl

#ln -s /usr/lib/libXi.3 /usr/lib/libXi.sl

#ln -s /usr/lib/libXm.4 /usr/lib/libXm.sl

#ln -s /usr/lib/libXp.2 /usr/lib/libXp.sl

#ln -s /usr/lib/libXt.3 /usr/lib/libXt.sl

#ln -s /usr/lib/libXtst.2 /usr/lib/libXtst.sl

5.Enable remote access (ssh) for Oracle user on all nodes.

6.Create file system for Oracle directories.

In the following samples, /mnt/app is a mounted file system for Oracle software. Assume there is a private disk c4t5d0 at 18 GB size on all nodes. Create the local file system on each node.

#umask 022

#pvcreate /dev/rdsk/c4t5d0

#mkdir /dev/vg01

#mknod /dev/vg01/group c 64 0x010000

#vgcreate /dev/vg01 /dev/dsk/c4t5d0

#lvcreate -L 16000 /dev/vg01

#newfs -F vxfs /dev/vg01/rlvol1

#mkdir -p /mnt/app

#mount /dev/vg01/lvol1 /mnt/app

#chmod 775 /mnt/app

7.Create Oracle cluster software home directory.

For installing Oracle cluster software on local file system, create the directories on each node.

#mkdir -p /mnt/app/crs/oracle/product/10.2.0/crs
